11 Chapter 1 Site Planning for ftserver T Series Systems1- ftserver T Series systems are fault-tolerant systems designed specifically for telecommunications service providers. In addition to its fault-tolerant system architecture, Stratus provides fault-hardened device drivers, which enhance application reliability and availability. For an overview of the information you need to know and the tasks you need to perform to prepare a site for ftserver T Series systems, see: Site Planning Overview Site Planning for Fault-Tolerant Systems Site Planning Checklist System Documentation For detailed site planning information, see: Chapter 2, Cabinet and Monitor Requirements Chapter 3, Space Planning Chapter 4, Electrical Power Planning Chapter 5, Network and Telephone Line Planning Chapter 6, ftserver T Series Rack Configuration Planning Appendix A, System Specifications Appendix B, Electrical Circuit and Wiring Information Appendix C, Standards Compliance Site Planning for ftserver T Series Systems 1-1

12 Site Planning Overview Site Planning Overview Site planning for fault-tolerant systems includes: Space planning Provide adequate space for the system or cabinet and for a desk or table to accommodate components outside a cabinet. Also provide enough space for servicing the systems and components. Purchasing an appropriate cabinet and monitor If you do not purchase a cabinet from Stratus, ensure that the cabinet you plan to use meets the system s requirements. If you do not purchase a monitor from Stratus, make sure that the monitor you plan to use meets ftserver T Series system requirements. Electrical (DC) power planning For DC-powered ftserver T 30 CO systems, provide a nominal input voltage of 48 VDC. The input voltage should be at least VDC and no more than 56.7 VDC. Electrical (AC) power planning For AC-powered ftserver T 30 AC and T 60 AC systems, determine AC power requirements as shown in AC-Powered Systems on page 4-7. Stratus does not supply or support uninterruptible power supplies (UPS) for ftserver T Series systems. Network and telephone line planning Provide sufficient network and analog telephone lines. Use the Site Planning Checklist on page 1-4 to ensure that you prepare your site properly for your ftserver T Series system and to track your site-preparation progress. For a list of other documents related to your ftserver T Series system, see System Documentation on page 1-7. During the site planning and preparation processes, work closely with your facilities group or contractor to determine space, power, and environmental requirements. Enlist their help to provide a suitable location with sufficient power, HVAC capabilities, and network and telephone connections. 1-2 Stratus ftserver T Series: Site Planning Guide (R001L)

13 Site Planning for Fault-Tolerant Systems If your system is covered by a service agreement and you need help with site planning, contact the Customer Assistance Center. If you have contracted with the CAC for installation of the system, contact them after you have prepared the installation site and moved the system to the site. For more information about the CAC, see Getting Help in the Preface or the CAC web site at: Refer to Appendix A, System Specifications, for ftserver T Series system specifications and to the Stratus ftserver Systems Peripherals Site Planning Guide (R582) for specifications of other components. Site Planning for Fault-Tolerant Systems In addition to the usual site planning tasks, such as planning sufficient DC electrical power and providing network connections, consider the following specific fault-tolerant features of ftserver T Series systems: Lockstep technology in ftserver T Series systems means that the systems contain redundant hardware. In the event of a component malfunction, the partner component is an active spare that continues normal operation. The failed component can then be removed and replaced without loss of data or service. In addition to planning for the duplicated power supplies, fans, and disk drives, often supplied by other servers, plan for replicated core system components including motherboards, processors, memory, I/O buses, and PCI adapters. Consequently, site planning includes planning for two CPU enclosures and for pairs of: I/O enclosures Ethernet network ports PCI adapters DC power inverters Power receptacles ftserver T Series systems can connect to the Stratus ActiveService Network (ASN). Connecting a system to the ASN allows the CAC to remotely diagnose, troubleshoot, and resolve problems online. Site Planning for ftserver T Series Systems 1-3

14 Site Planning Checklist To enable connectivity to the ASN, which allows the CAC to remotely manage the system, the system contains an external modem. With an external modem, ASN connectivity is only possible if the operating system is operational. Site Planning Checklist Referring to the information in this document, answer the questions in the following sections. Planning for ActiveService Network Connectivity Do you have an external analog telephone line available for the external modem to connect to the Stratus ASN? NOTE A dedicated phone line provides the most reliable service. ASN calls routed through a PBX might be slow due to load on the PBX, or might not complete successfully due to disconnections. If you must use a PBX, do not route the telephone extension through a switchboard; instead, provide a direct-dial analog number. Do you have an additional telephone line and telephone near the operator s station for voice communications when calling for support? Planning for Optional Components Does your system include any of the following optional PCI adapters for network communications or external storage connectivity? If so, indicate how many of each and plan network connections accordingly. Adapter Number of Adapters U574 Dual-Port Fiber Gigabit Ethernet Adapter U575 Dual-Port Copper Gigabit Ethernet Adapter U918 Four-Port T1/E1 PCI Adapter U532 Fibre Channel PCI Adapter Will you supply your own monitor, or will you use a monitor supplied by Stratus? Is the monitor rack-mountable, or do you need to provide a table or desk? Do you require a keyboard and mouse? 1-4 Stratus ftserver T Series: Site Planning Guide (R001L)

15 Site Planning Checklist NOTE Use only the USB keyboard and mouse supplied by Stratus. Does your system include any D548 storage enclosures? Does your system include any external tape drives? Do you need to provide a table or desk? Each core I/O enclosure in an ftserver T Series system contains an external SCSI port that you can use to connect the system to tape drives. The system supports up to three tape drives per core I/O enclosure. Planning Power for ftserver T 30 CO Systems For ftserver T 30 CO systems, provide a nominal input voltage of 48 VDC. The input voltage should be at least VDC and no more than 56.7 VDC. If you have an optional tape drive, you must provide an external AC power source for it at the site. What are the lengths and types of the power cables provided with your system? What are the lengths and types of the ground cables provided with your system? Will you use a tape drive, D548 storage enclosures, or other optional, AC-powered components? Planning Power for ftserver T 30 AC and T 60 AC Systems What optional, AC-powered components will you use? What are the AC power requirements of your system? Is the AC power service wired properly? What are the lengths and types of the power cords provided with your system? Planning Space for Your System Will your system and its external components fit where you plan to place them? What is the height of the cabinet you will use, and what is the total height of the systems and components that will be installed in the cabinet? How many systems and optional components will be housed in the cabinet? What components will be located outside the cabinet? What are the lengths and types of all interface and communication cables provided with your system? Have you created a sketch of how the system will be arranged at the installation site? Consider the available cable lengths, the placement of external devices, and the location of network and voice communication connections. Site Planning for ftserver T Series Systems 1-5

16 Site Planning Checklist On the sketch, show the following: Location of the system and its external components Power cords, and telephone and interface cables Locations of DC and AC power receptacles, phone jacks, Ethernet jacks, switches, and/or hubs NOTE Make sure that all cords and cables are long enough to reach between their respective components and connectors.

21 Chapter 2 Cabinet and Monitor Requirements2- If you are supplying your own cabinet and monitor for use with ftserver T Series systems, see the following requirements: Cabinet Requirements Monitor Requirements If you are not supplying your own cabinet and monitor go to Chapter 3. Cabinet Requirements If you are providing your own cabinet for the ftserver system, make sure the cabinet contains a 19-in. wide rack that meets the Electronic Industries Association (EIA) 310-D standard. For system cabinet requirements, refer to one of the following sections: Cabinet Requirements for All ftserver T Series Systems Additional Cabinet Requirements for ftserver T 60 AC Systems Additional Cabinet Requirements for ftserver T 30 Systems The following considerations apply to systems in cabinets. Elevated Operating Ambient Temperature- If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might Cabinet and Monitor Requirements 2-1

22 Cabinet Requirements have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern. Cabinet Requirements for All ftserver T Series Systems Use a cabinet that is either 24U or 38U high. One U equals 1.75 inches (4.45 cm). A cabinet depth of 1000 mm ensures that you can close the rear door. Make sure that: The cabinet contains two front and two rear vertical EIA rails, one in each corner of the cabinet, that have the EIA universal square-hole pattern as defined in the EIA 310-D specification. NOTE ftserver T Series systems do not support the EIA wide square hole pattern. The front vertical rails extend at least 0.5 in. (1.27 cm) beyond the inside edge of the accessory leg, if present, to allow the mounting rails to be fitted. See Figure 2-1. The distance between the front vertical rails and the inside of the front door is at least 3.0 in. (7.62 cm). The distance between the rear of the system chassis and the inside of the rear door is at least 6.0 in. (15.24 cm). The vertical mounting rails are plated, or some other method is used to ensure continuity for grounding between installed equipment. Cable-management brackets are provided to support and constrain data and power cords so that the cables do not interfere with air flow out of the rear of the enclosures, and so that the connectors do not disconnect or break. The cabinet provides enough stability so that system components pass Telcordia GR-63-CORE Section 4.4 regulations for earthquake vibration (Zone 4), operation vibration, and transport vibration. To prevent stray voltages, all components are grounded together through the vertical mounting rails to the cabinet frame, and then to ground and also to local building ground. To ensure signal quality, use a grounding cable provided by Stratus for local building ground. There is a plan for maintaining cables and wires to the cabinet by either running them under the floor or placing them overhead in a power bus. Air flows through the cabinet from front to back. Air does not recirculate within the cabinet. Filler panels cover any unused rack space to prevent air recirculation. 2-2 Stratus ftserver T Series: Site Planning Guide (R001L)

23 Cabinet Requirements Blockers are installed between the vertical mounting rails and the side panels at the rear of the cabinet. Vents are evenly distributed on the front and rear doors and comprise at least 63% of the surface area. Door frame width must be kept to a minimum to maximize the available open area. NOTE If your cabinet does not have vented front and rear doors, remove the doors from the cabinet while the ftserver system is operating. The final installation conforms to all emission, immunity, safety, and other applicable regulations. Figure 2-1 shows the required rail clearance between the front vertical rails and the inside edge of an accessory leg. Cabinet and Monitor Requirements 2-3

25 Monitor Requirements Additional Cabinet Requirements for ftserver T 60 AC Systems The ftserver T 60 AC system consists of a 10U system, rack mountable in a customer-supplied cabinet. Make sure that: A 24U cabinet can support at least 900 lb (410 kg) to support allowed configurations and components for a 24U cabinet. A 38U cabinet can support at least 1100 lb (500 kg) to support allowed configurations and components for a 38U cabinet. The distance between the front and rear vertical rails is 27 in. (68.58 cm). The vertical mounting rails accept 10/32 screws. Additional Cabinet Requirements for ftserver T 30 Systems The ftserver T 30 system consists of a 6U system, rack mountable in a customer-supplied cabinet. Make sure that: The distance between the front and rear vertical rails is between 24.5 in. and 30 in. (62.23 cm and cm). The vertical mounting rails accept M-5 cage nuts and mounting hardware. Monitor Requirements If you are using a monitor that is not supplied by Stratus, make sure that: The monitor accepts universal VAC, Hz power. The VGA-compatible SVGA connector has a 15-pin D-sub connector at the cable end. The power cord for the monitor is long enough to reach the power source. The plug type on the power cord is compatible with the external power source at the site. NOTE Use the keyboard and mouse provided by Stratus. Cabinet and Monitor Requirements 2-5

27 Chapter 3 Space Planning3- For information about planning sufficient space for your ftserver T Series system, see: Room Requirements Planning for Cables Room Requirements To ensure that the installation site provides a properly equipped, cooled, and sized environment, make sure that the site: Provides clearances for air circulation and servicing the system Locate the front and rear of the system at least 2.5 ft. (0.76m) away from walls and other obstructions. Maintains reasonable temperature and humidity levels and has a thermometer and humidistat to monitor room temperature and humidity Is as free of dust as possible Dust buildup in the system can impede air circulation and heat transfer, causing components to become less reliable as the ambient temperature rises. Provides a table or desktop for external devices such as a telephone, tape drives, and an external monitor or LCD display, keyboard, and mouse Provides cutouts in the floor for routing cables, if the site has an elevated floor! CAUTION Do not place the system in an area of high electrostatic discharge. Static electricity may damage components. Do not locate components near transformers or other electromagnetic devices. Space Planning 3-1

28 Planning for Cables Planning for Cables To accommodate cables from the ftserver T Series system, make sure to provide: Two telephone lines: One telephone line for use when calling for service One telephone line for the ASN connection to the modem Modem placement within 39 in. (1m) of the ftserver T Series system, unless you provide your own AC power and signal cables Ethernet jacks, switches, or hubs as needed For DC-powered ftserver T 30 CO systems, provide a nominal input voltage of 48 VDC. The input voltage should be at least VDC and no more than 56.7 VDC NOTE DC power cables generally have a wider diameter than AC cables. Be sure to leave enough space for the wider curves these cables require. For AC power: sources as required NOTE Stratus does not provide uninterruptible power supply (UPS) units for ftserver T Series systems. For optional components: AC wall outlets within reach of the power cords from the components, or use PDUs 3-2 Stratus ftserver T Series: Site Planning Guide (R001L)

31 Chapter 4 Electrical Power Planning4- Stratus ftserver T 30 central office (CO) systems connect to DC power sources. ftserver T 30 AC and ftserver T 60 AC systems connect to AC power sources. For information about planning appropriate electrical power for your ftserver T Series systems, see: Redundant Power Sources Grounding Requirements DC-Powered Systems AC-Powered Systems AC Power Cords Supplied by Stratus Redundant Power Sources All ftserver T Series systems require at least two separate and independent electrical power sources. Think of them as the A-side power source and the B-side power source. Either side must be capable of continuing to provide power if power to the other side is lost. DC-powered systems require two DC power sources, and AC-powered systems require two AC power sources. Grounding Requirements The ftserver T Series system obtains an earth reference ground via independent ground connections to the cabinet frame. Ensure that a high-integrity safety-ground conductor is installed as part of the wiring system (in accordance with Bellcore standards).! WARNING Incorrect grounding can cause severe personal injury and extensive equipment damage. See Grounding Considerations in Appendix B for a more complete discussion of ftserver T Series grounding. Electrical Power Planning 4-1

32 DC-Powered Systems DC-Powered Systems You must provide two separate DC power sources to supply power to two DC-to-AC power inverters. Both inverters supply AC power to the ftserver T 30 CO systems. One of the sources must also provide power for the ASN modem and a V128 monitor unit, if purchased. The inverter units contain no user serviceable parts. This section includes the following topics: DC Power Connection Information DC Operation Power Service Requirements AC Power Service Requirements DC Power and Ground Cables DC Power Connection Information Stratus supplies power cables to connect each inverter s DC input cable to the CO power supply. Figure 4-1 shows the DC input and ground cables on the rear of the DC inverter assemblies. Figure 4-1.

33 DC-Powered Systems NOTE User-supplied DC power cables that connect directly from the CO supply to the DC inverter s DC input cable must use an Anderson Power Products connector (Anderson part number SBS50BLU#6-BK) and two contacts (Anderson part number 1339G2-BK) at the inverter end. User-supplied DC power cables that connect directly from the CO supply to the rear of the DC inverter must use a FCI- Burndy ring lug connector (Burndy part number YAV6CL2TC14FX) at the inverter end. Each inverter provides AC power to the system components through AC output Y cords. One end of each Y cord provides AC power to one side of the system. The other end provides AC power to external components. One cord has a T-plug adapter to provide one additional AC outlet. Figure 4-2 shows how the AC output cables and splitters are connected to an ftserver T 30 CO system. NOTE The AC output cord T-plug adapter can be connected to either the A-side AC output cord or the B-side AC output cord. The DC power inverters support only the ftserver T 30 CO system s CPU, I/O, monitor, and modem units. Only attach monitors supplied by Stratus to the DC inverters.! CAUTION Do not connect tape drives, D548 storage enclosures, customer-supplied monitors, or other AC-powered components to the DC power inverters. Doing so may damage the inverters and the attached components. Connect the tape drive directly to an AC wall outlet. The D548 storage enclosure requires two separate power sources. Connect the two power cords from the storage enclosure directly to two electrically separate AC wall outlets. Electrical Power Planning 4-3

WARNING When ftserver T Series AC systems operate at voltages greater than 120 volts AC, the systems have high leakage current (greater than 3.5 ma). Stratus ships power cords with locking connectors for voltages higher than 120V. Use these locking connectors to ensure that the excess current is safely conducted to ground. Use the following worksheets to determine AC power requirements for the site. In Table 4-6, determine the power requirements at the A-side power source. The A-side power source provides power to one side of each system and D548 storage enclosure, as well as to components that do not require two sources of power: rack-mounted tape-drive enclosures, a modem, and an LCD monitor unit. 4-8 Stratus ftserver T Series: Site Planning Guide (R001L)

39 AC-Powered Systems In Table 4-7, determine the power requirements at the B-side power source. The B-side power source provides power to the other side of each system and D548 storage enclosure. In Table 4-8, determine the power requirements for components outside of the cabinet. These components can share a power source with the A-side or B-side components.! WARNING Wiring must meet ftserver T Series system AC system needs and comply with local safety codes and requirements. See Appendix B, Electrical Circuit and Wiring Information for electrical circuit and wiring information. To determine AC power requirements 1. In the Quantity column, write the number of each type of component. 2. Multiply the entry in the Quantity column by the number in Power (Watts) column, and enter the result in the AC Power (Extended) column. 3.

The two power sources must at least be powered by separate AC power distribution circuit breakers and, if possible, be independent of each other beyond that level. The more electrical separation between the two power sources, the less likely that they will both fail at the same time. Due to redundancy in ftserver systems, power to either side of the system keeps duplexed components of the system operational. NOTE Stratus does not supply or support UPS equipment for ftserver T 30 or T 60 systems. The A-side power source provides power to each system as well as to optional components such as a V128 1U LCD monitor unit or tape drive. Electrical Power Planning 4-11

42 AC-Powered Systems The B-side power source also provides power to each system, in stand-by mode (the B-side power source is used if power to the A-side source is interrupted). The wattage that the A-side power source must supply is always equal to or greater than the wattage the B-side power source must supply.

69 Appendix B Electrical Circuit and Wiring InformationB- For the electrical circuit and wiring information that you need to provide to the contractor and/or facilities personnel responsible for wiring the power at the system installation site, see: DC-Powered ftserver T 30 CO Systems AC-Powered ftserver T 60 AC and T 30 AC Systems DC-Powered ftserver T 30 CO Systems The ftserver T 30 is designed to run on DC power. A DC power inverter provides AC power to the system and its components. Figure B-1 shows the rear of the inverter. The following sections provide electrical and wiring information for ftserver T 30 CO systems: Fault Protection Grounding Considerations Circuit Wiring Diagrams DC Power Cables and Connectors Electrical Circuit and Wiring Information B-1

70 DC-Powered ftserver T 30 CO Systems Figure B-1. AA-P86600 DC-to-AC Inverter - Rear View tlc043a 1 B-side DC inverter 4 A-side DC inverter 2 A-side DC input cable 5 Chassis ground cable 3 B-side DC input cable Fault Protection Each customer replaceable unit (CRU) in the ftserver T30 system contains fault/overload current protection. The two DC inputs to each DC inverter CRU are protected by fuses for protection against internal faults. However, the system relies on the power distribution system at your site for protection against potential faults in the power cords. You must use circuit breakers in each power distribution branch feeding the system. Grounding Considerations The ftserver T 30 system obtains an earth reference ground via independent ground connections to the cabinet frame. Ensure that a high-integrity safety-ground conductor is installed as part of the wiring system (in accordance with Bellcore standards). The international safety standard (EN-60950) for electronic data processing (EDP) equipment also requires a ground conductor, but calls it a potential earth (PE) ground. Depending upon local conditions, ground potentials may differ between the system cabinet and any peripheral devices connected to the system cabinet. B-2 Stratus ftserver T Series: Site Planning Guide (R001L)

71 DC-Powered ftserver T 30 CO Systems The ftserver T 30 CO system cabinets must connect to a common ground point (ground window) to ensure signal integrity and the safety-ground connection. To meet this requirement, an ftserver T 30 CO cabinet is connected to the ground window by one or two green-wire safety-ground conductor leads (#4 gauge wire), each of which can handle 60A fault current. A star ground, shown in Figure B-2, is often used to obtain the same earth reference ground. Each earth reference ground, such as the system cabinet ground, is returned separately to a common point where a 0-volt earth ground exists. The star ground ensures that all equipment is at the same potential and that no noise or safety problems associated with an unpredictable or uncharacterized grounding system will occur. Figure B-2.

73 AC-Powered ftserver T 60 AC and T 30 AC Systems DC Power Cables and Connectors Stratus supplies tested and approved cables and connectors for the ftserver T 30 CO system. Table 4-2 provides descriptions and part numbers. NOTE User-supplied DC power cables that connect directly from the CO supply to the DC inverter s DC input cable must use an Anderson Power Products connector (Anderson part number SBS50BLU#6-BK) and two contacts (Anderson part number 1339G2-BK) at the inverter end. User-supplied DC power cables that connect directly from the CO supply to the rear of the DC inverter must use a FCI- Burndy ring lug connector (Burndy part number YAV6CL2TC14FX) at the inverter end.! WARNING User-supplied power or ground cables must meet ftserver T 30 system needs and must comply with local safety codes and requirements. AC-Powered ftserver T 60 AC and T 30 AC Systems The following sections provide electrical and wiring information for ftserver T 60 AC and T 30 AC systems: Grounding Considerations Circuit Wiring Diagrams Electrical Power Connectors Grounding Considerations The system obtains an earth reference ground through the power cords attached to the system. Similarly, each peripheral device connected to the system obtains ground through its power cord. For each peripheral device, you must ensure that a high-integrity safety-ground conductor is installed as part of the wiring system (in accordance with U.S. national electric code NFPA 70 or the equivalent). The international safety standard (EN60950) for electronic data processing (EDP) equipment also requires a ground conductor, but calls it a protective earth (PE) ground. Electrical Circuit and Wiring Information B-5

74 AC-Powered ftserver T 60 AC and T 30 AC Systems Depending upon local conditions, ground potentials may differ between the system base and any peripheral devices connected to the system base. All grounds in the system must return to the same reference point in the power distribution system, as close as possible to zero (0) volt potential relative to earth reference ground. Earth reference ground is typically a metal stake in the ground to which the ground conductors from one or more buildings are attached. As shown in Figure B-4, a star ground is often used to obtain the same earth reference ground. Each earth reference ground, such as the system base ground, is returned separately to a common point where a zero-volt (0V) earth ground exists. The star ground ensures that all equipment is at the same potential and that no noise or safety problems associated with an unpredictable or uncharacterized grounding system will occur. Figure B-4. Star Ground Example To monitor 3 Earth reference ground (0V) 2 To ftserver system Circuit Wiring Diagrams The following circuit wiring diagrams show how the hot, ground, and/or neutral AC signals should be connected to the system s power input plug: Figure B-6 illustrates a single-phase, 120-volts AC circuit connection (for ftserver T 30 AC only). Figure B-7 illustrates a single-phase, 240-volts AC circuit connection. Figure B-8 illustrates a split-phase, 120/240-volts AC circuit connection. Figure B-9 illustrates a three-phase, 208-volts AC, Y-, or -source circuit connection, phase-to-neutral. B-6 Stratus ftserver T Series: Site Planning Guide (R001L)

75 AC-Powered ftserver T 60 AC and T 30 AC Systems Figure B-10 illustrates a three-phase 208-volts AC, Y-, or -source circuit connection, phase-to-phase. Figure B-11 illustrates a three-phase 380-volts AC, Y-, or -source circuit connection, phase-to-neutral. The figures in this appendix, label the power inputs for the ftserver system as X and Y (as shown in Figure B-5) to eliminate any ambiguities in the nomenclature. For single-phase applications, the X input is connected to the L (Line) hot input, and the Y input is connected to the N (Neutral) input. However, for split-phase or three-phase applications, the X and Y inputs are connected to L1, L2, or L3 (separate lines). Therefore, for split-phase or three-phase applications, both X and Y can be electrically hot with respect to the system base (earth reference ground). Figure B-5 shows the physical locations of the X and Y inputs on the system base. Figure B-5.
